a. Main Functions:

1) Method of Contact Angle Measurement (Automatic quantitative droplet application, droplet accuracy: 0.1ul, fully automatic real-time testing):

Static Drop Method (Utilizing OpenCV graphic contour analysis software, real-time automatically tests the left and right angles as well as the average angle of the liquid drop, timing test and analysis data after droplet formation until the test ends and timing stops), providing real-time test curves and Excel data lists, with image saving function.

Dynamic Testing: Drop Method (Dynamic Testing: Forward Angle, Reverse Angle, Inclination Angle) (Utilizing Opencv's Graphical Contour Analysis Software, Real-time Automatic Dynamic Analysis to Determine Forward Angle, Reverse Angle, Inclination Angle)

Wetting Method: Contact angle test of the material immersed in a liquid

2) Measure surface tension:

Drop Weight Method (for measuring interfacial tension, which can test dynamic interfacial tension), CMC (Drop Weight Method)

Observe and measure the shape and size of droplets (using the pendant drop method) to test the surface tension value of liquids. The tension test range is 0.001 mN/m to 1000 mN/m.
